We really enjoyed our stay at Alex's place, it was even better than we thought it would be from the photos and Alex is a great host who was very responsive from first booking to checkout!
Everything was very comfortable and well equipped and the view from the apartment of the Iconsiam mall across the river especially at night was always nice to come back to see. We even caught a brief fireworks show at times during our stay. Also great views from the rooftop pool and gym, that's well equipped and maintained.
Grab and taxis are easy to get from out front of the building and you are walking distance to the ferry, bus or BTS.
If you stay here, definitely try the historic Chinese food spot right across the street from the lobby, the staff are very nice and the food is delicious -- after going once, it became out goto spot. The 7/11 outside right downstairs was very convenient too.
We would definitely stay with Alex again, he also helped arrange a very competitive price for a transfer to the airport so we wouldn't have to worry about rain during our departure -- they picked us up right at the building roundabout smoothly.
Overall a great spot if you are visiting Bangkok, more spacious for the price than several others we were looking at --- very happy with our choice!
